INLET-VALVE FOR INTERNAL-COMBUSTION ENGINES.`

Specification of Letters Patent.

Patented Aug. 25, 1914.

Application filed January 28, 1914. Serial No. 815,078.

To all whom it may concern:

Be it known that I, WILLIAM SMOKE, a citizen of the United States,residing at To dianapolis, in the county of Marion and State of Indiana,have invented a new and useful Inlet-Valve for Tnternal-CombustionEngines, of which the following is a specification. n

The object of my invention is to produce an effective means forsupporting the inlet valve casing of an internal combustion engine insuch manner that the inlet valve may be readily accessible.

The accompanying drawings illustrate my invention.

Figure 1 is a fragmentary axial section practically full-size of anengine embodying my invention; Fig. 2 a side elevation in partialvertical section at right angles to the plane of Fig. l; Fig. 3 a planof the parts shown in l*1 ig. 2; and Fig. 4- a perspective of one of thefastening hooks.

In the drawings, indicates the main body of the engine provided with apassage 11 which, at its inlet end, is provided with an outwardlypresented shelf 12 flanked by a threaded opening 14. Dropped into theopening 14 and seating upon the shelf 12 is a valve ring 15 providedwith a central sleeve 1G which forms the support for the stem l? of theValve 1S seated in the innerl end of ring 15. Surrounding sleeve 1T is aspring 19 which acts upon stem 17 to normally close the same. Threadedinto the opening 14 is a valve-ring clamping member Q1 which serves toclamp the valve ring 15 in place. This ring Q1 is formed upon its outerend to receive a packing gasket Q2 whichv lies between it and the openlower end of an inlet easing TVithin the casing Q3 the clamping ring 21is provided with a plurality of' axially projecting lugs Qi by means ofwhich the clamping ring may be readily tightened andloosened. Clampingring Q1 is provided with an inwardly projecting and undercut flange Q5beneath .which may be projected arc-shaped hooks 2G carried by the lowerend of a pair of clamping bolts 27, the threaded shanks of which areprojected through openings 2S in casing 23 and adapted to receive nutsQ0.

The inlet. casing 23 is provided in its upper part with a chamber 31.the open upper end of' which is covered by a readily removable cap 32conveniently held in place by a spring finger 33. Projected upwardlyinto chamber 31, through a bushing 34, is the valve stem 1i" andpivotally mounted within chamber 3l isa valve operating lever one end ofwhich engages the stem 17 and the other end of which is provided with adownwardly presented cup 3G arranged in alinement with the bore of aboss 3T extending through the inlet passage leading into the mainlchamber of the casing 23,

the arrangement being such that a valve-i,

operating rod 38, projected upwardly through the bore of boss 37, mayenter the cup 3G of lever l? or convenience in primingthe engine, llprovide the casing 23 at an easily accessible point witha primingopening i0 normally covered by a swinging cover plate 41 provided with aconvenient thumb pieoe 42.

- lln use, the valve ring 15 with its valve is dropped into place uponshelf 1:2 and ring 21 is then screwed firmly to place sons to hold thering 15 in proper position. Thereupon easing 2% is placed upon gasket 25and the bolts 2T are passed downwardly through the opening 2S. thehooked ends being first swung inwardly so as to pass beyond the undercutlower edge of flange 25 and then being swung outwardly so as to bringthe hooks 26 beneath the flange. Thereupon the nuts Q9 are screwed downso as to draw the hooks, Q6 upwardly beneath flange 25 and drive thenuts downwardly upon easing 223 so as to firmly hold it in place. At anytimel that the valve needs adjustment or inspection, nuts 2f) may bereadily loosened and bolts 27 withdrawn or swung inwardly whereuponeasing '23 may be lifted from place without the necessity of anyseparation or adjustment Aof the connection between the operating rod 38and the valve, the down ardly presented cup 36 withdrawinf freely fromthe upper end of rod 35B.

ll claim as my invention:

1. The combination with an engine and a valve therefor. of' a clampingring for said valve provided with an inwardly projected flange, a casingmember arranged to cover the valve, and a casing clamp comprising ahooleshaped member projected through the casing member and engaging theinwardly projected fiange of the clamping ring said hook shaped memberhaving a threaded outer end and a nut threaded thereon and engaging thecasing.

2. The combination with an engine and a valve therefor, of a clampingring for said valve provided with an inwardly projected flange, a casingmember arranged to cover the valve, and a casing clamp comprising ahook-shaped member projected through the casing member and engaging theinwardly projected flange of the clamping ring.

3. The combination with an engine having a valve opening, of a valveassociated with said opening, a casing surrounding said opening, andclamping means for said casing, said clamping means comprising a bolthaving ahook-shaped inner end projected through the casing and engagingwith a portion carried b the engine within the casing.

4:. The com ination with an engine having a valve opening, of a valveassociated therewith, a casing encompassing said valve, avalve-operating member, an intermediate connection, carried by thecasing, operatively connecting the-valve operating member and the valveand engaging the valve operating member in one direction only, and meansfor clamping the casing in position said means comprising a lhook-shapedmember projected through the casing and engaging with a portion withinthe casing.l

5. The combination with an engine having a valve opening, of a valveassociated therewith, a casing encompassing said valve and removableindependently of the valve, a valve-operating member, an intermediateconnection, carried by` and within the casing, operatively connectingthe valve operating member and the valve and engaging the valveoperating member in one direction only,.and means for clamping thecasing in osition.

6. T e combination with an engine having a valve opening, of a valveassociated therewith, a clamping ring threaded into said opening and campng the valve in place, said clampin ring having an inwardlyprojecting flange, a casing encompassing said valve, a hook projectedthrough the casing into engagement with the flange of the clampingring,a nut mounted on the outer end of the hook and engaging the casing toclamp it in place, a valve-operating lever mounted in the casing andengaging4 the valve 1n one direction, and a valve operating memberprojected into the casing and engaging the valve operating lever iny onedirection. L

7. The combination with an engine having a valve opening, ofxa valveassociated therewith, av clamping ring threaded into said opening andclamping the valve in place, said clamping ring having an inwardlyprojecting flange, a casing encompassing said valve, a hook projectedthrough the casing into engagement with the iiangc of the, clampingring, and a nut mounted on the outer end of the hook and engaging thecasing to clamp it in place.

8. The combination of an engine having a valve opening, a valve ringmounted therein, a valve associated with and carried by said valve ring,a casing removably mounted on said engine and into which the valve stemrojects, a valve-operating member also projecting into said casing, anintermediate connection carried by and within the casing and operativelyconnecting the valve-operating member and the valve stem, and means forclamping the casing in position, said means when released permitting thecasing and intermediate connection to be removed while leaving the`valve-operating member and valve in place.

l'n witness whereof, I have hereunto set my hand at Indianapolis,`Indiana, this twentysixth day of January, A. D. one thousand ninehundred and fourteen.
